+# ADR-0015: Beoordeling escalation reassigns via an external-worker task
+
+- **Status:** Accepted
+- **Date:** 2026-07-17
+- **Deciders:** Respellion engineering
+- **Relates to:** S-14 (#15); proposal #98. Builds on ADR-0009 (external-task worker / Workflow
+  Client), ADR-0013 (behandel-portal wiring, the `Beoordelen` user task), ADR-0014 (the boundary-event
+  pattern on `Beoordelen`).
+
+## Context
+
+S-14 escalates a beoordeling that a behandelaar does not pick up in time: after 14 days the case must
+move to the `teamlead` role (PRD §5, flow 5). The `Beoordelen` user task already exists, claimable by
+the `behandelaar` candidate group; the teamlead role is seeded in the medewerker realm.
+
+Two forces shape this.
+
+1. **The task must stay open.** Escalation changes *who may claim* an unclaimed beoordeling, not the
+   work itself — so the timer must be **non-interrupting**: the `Beoordelen` task keeps running while
+   escalation happens alongside it.
+2. **Reassigning an open task's candidate group needs code.** Flowable cannot rewrite the candidate
+   groups of an already-open user task from BPMN XML alone — that requires either a Java delegate/listener
+   embedded in the engine, or an out-of-process actor driving the REST API. The repository has held a
+   "stock Flowable image, no custom jars; the Workflow Client is the only code that talks to Flowable
+   (§8.2)" posture since ADR-0009.
+
+## Decision
+
+**A non-interrupting `P14D` boundary timer on `Beoordelen` fires an external-worker task
+(`BeoordelingEscaleren`); the Workflow Client reassigns the still-open `Beoordelen` task from the
+behandelaar group to teamlead.**
+
+- **Modelled in BPMN, driven by an external worker.** The timer routes a parallel token to an
+  `external-worker` service task on the `BeoordelingEscaleren` topic, ending at a dedicated "Beoordeling
+  geëscaleerd" end event. The model owns *when* escalation happens; the Workflow Client — the only code
+  that talks to Flowable (§8.2) — owns *how* the reassignment is applied, exactly as `OpenZaakAanmaken`
+  delegates the ZGW call (ADR-0009). No custom code runs inside Flowable.
+- **Reassignment is a candidate-group swap.** The escalation worker finds the still-open `Beoordelen`
+  task in the escalating instance (task query by `processInstanceId` + `taskDefinitionKey`), adds
+  `teamlead` as a candidate group via the task identity links, then removes `behandelaar`. The task now
+  belongs to the teamlead; its history and variables are untouched.
+- **Best-effort, mirroring beoordeling and withdrawal.** If the task is no longer open — the behandelaar
+  completed it in the window before the timer fired — the reassignment is a no-op. A failed reassignment
+  leaves the escalation job un-completed so Flowable redelivers it (§8.6), consistent with the
+  `OpenZaakAanmaken` worker.
+- **Segregated interface.** The escalation methods live on `IBeoordelingEscalatieClient`, separate from
+  the `OpenZaakAanmaken` worker's `IExternalWorkerClient`, so the OpenZaak worker never sees escalation
+  (interface segregation). Both are implemented by the one `FlowableWorkflowClient`.
+
+## Consequences
+
+**Positive**
+
+- The escalation trigger is visible in `registratie.bpmn`; Flowable stays a stock image, and the
+  Workflow Client remains the sole Flowable client (§8.2 upheld, not bent).
+- Reuses the external-worker mechanics (topic acquire/complete, hosted pump, per-tick scope,
+  redelivery-on-failure) wholesale — the new code is one client capability, one processor, one pump.
+- Escalation latency is bounded by the worker's poll interval (seconds) — negligible against a 14-day
+  timer.
+
+**Negative / costs**
+
+- Escalation is two REST hops (add teamlead, remove behandelaar) rather than one atomic update; between
+  them the task is briefly claimable by both groups. Harmless at these volumes, and the pair is idempotent
+  on redelivery.
+- The Flowable identity-link and management-job REST shapes are validated live (verify-domain fires the
+  timer early via the management API), not in the Workflow Client's unit tests, which stub the HTTP
+  exchange and assert only the request shape — consistent with ADR-0009 and ADR-0014.
+
+## Alternatives considered
+
+- **Flowable timer/task listener (Java delegate).** Reassign in-engine when the timer fires. Rejected:
+  it needs a custom jar in Flowable, breaking the stock-image, REST-only posture and adding a build/deploy
+  surface to the engine for no capability the external-worker route lacks.
+- **Interrupting timer that re-creates the task for teamlead.** Cancel `Beoordelen` and start a fresh
+  teamlead task. Rejected: it loses the task's identity/history and complicates correlation, where a
+  candidate-group swap on the same task expresses "the same work, now the teamlead's" directly.

+# ADR-0016: Diploma eligibility is a DMN evaluated inline as a BPMN businessRuleTask
+
+- **Status:** Accepted
+- **Date:** 2026-07-17
+- **Deciders:** Respellion engineering
+- **Relates to:** S-13 (#14); proposal #100. Builds on ADR-0009 (external-task worker / Workflow
+  Client), ADR-0014/0015 (the boundary-event and routing constructs on the registratie process).
+
+## Context
+
+S-13 adds flow 4: a foreign diploma must get an extra CBGV-advies assessment before beoordeling
+(PRD §5). The eligibility decision — domestic goes straight to beoordeling, foreign routes through
+CBGV-advies — needs a home. The Flowable REST app bundles a DMN engine, and the same
+`repository/deployments` machinery that deploys `registratie.bpmn` can deploy a `.dmn`. §8.2 makes
+the Workflow Client the only code that talks to Flowable; the PRD frames the workflow as "BPMN + DMN
+governing the registration workflow" (Flowable as a peer orchestration module).
+
+The issue's wording ("a DMN decision table evaluated by the Domain Service via Workflow Client")
+suggests the domain reaches into Flowable's DMN API to evaluate the decision and feeds the result
+back. That is one option; it is not the only one, and it is not the cleanest.
+
+## Decision
+
+**The diploma-eligibility DMN is deployed to Flowable and evaluated inline by the registratie process
+as a `businessRuleTask`; an exclusive gateway routes on its output. The domain's only new job is to
+carry the diploma origin and pass it into the process as a start variable.**
+
+- **The decision lives in the workflow.** `workflows/diploma-eligibility.dmn` maps `diplomaOrigin`
+  → `route` (`Buitenlands` ⇒ `CBGV_ADVIES`, otherwise `DIRECT`). A `businessRuleTask`
+  (`flowable:type="dmn"`, `decisionTableReferenceKey=diploma-eligibility`) runs it between
+  `OpenZaakAanmaken` and `Beoordelen`, and an exclusive gateway sends `CBGV_ADVIES` through a new
+  `CBGVAdvies` user task before `Beoordelen`, `DIRECT` straight there.
+- **The domain carries the input, not the decision.** The `Registration` aggregate gains a
+  `DiplomaOrigin` (Binnenlands/Buitenlands); `SubmitRegistration` passes it to
+  `StartRegistrationProcessAsync`, which sets it as the `diplomaOrigin` start variable. The domain
+  never evaluates the DMN and never learns the route — that is the process's concern.
+- **Deployed like the BPMN.** The DMN is version-controlled in `workflows/` and deployed to the DMN
+  engine by the same `flowable-init` step (via `dmn-api/dmn-repository/deployments`), staged into the
+  `fl-bpmn` volume alongside the BPMN.
+
+## Consequences
+
+**Positive**
+
+- The eligibility rule is a first-class, inspectable workflow artefact (matching the PRD's BPMN+DMN
+  framing); business users can read/adjust the decision table without touching domain code.
+- §8.2 stays clean: the Workflow Client remains the only code talking to Flowable, and the decision
+  runs inside the process the client already started — no domain→Flowable round-trip for a decision.
+- The domain change is minimal and additive: one value on the aggregate, one start variable.
+
+**Negative / costs**
+
+- Deviates from #14's literal "evaluated by the Domain Service via Workflow Client" wording (noted on
+  the issue). The outcome — DMN decides eligibility, foreign diplomas get the CBGV step — is unchanged.
+- The DMN and its `businessRuleTask` wiring are validated live (verify-domain drives a foreign
+  registration through CBGV-advies and a domestic one straight to beoordeling, exercising both
+  branches), not in unit tests — consistent with ADR-0009/0014/0015. The domain unit/acceptance tests
+  cover only that the origin is carried into the process.
+
+## Alternatives considered
+
+- **Domain evaluates the DMN via the Workflow Client** (the issue's wording). Rejected: it couples
+  the domain to Flowable for a decision and splits the routing across two places (domain computes,
+  BPMN branches), for no benefit over letting the engine that owns the process own the decision.
+- **Eligibility rules in domain C#.** Rejected: it moves a governable business decision out of the
+  DMN the PRD calls for, and hard-codes what the reference app is meant to demonstrate as data.

+## S-14 — Beoordeling escalation: 14 days unclaimed → teamlead (#15, ADR-0015)
+
+A beoordeling a behandelaar does not pick up within 14 days escalates to the teamlead. A
+non-interrupting boundary timer on the `Beoordelen` task fires a `BeoordelingEscaleren` external task;
+the domain's escalation worker reassigns the still-open task's candidate group from `behandelaar` to
+`teamlead`, so it moves from the behandelaar werkbak into the teamlead's. The `Beoordelen` task keeps
+its identity throughout — only who may claim it changes.
+
+The timer is 14 days, so the demo fires it early through Flowable's management API (exactly what the
+verify-domain check automates):
+
+```bash
+# 1. Submit at the self-service portal (http://localhost:8140/, jan-burger / test123). The case
+#    parks at Beoordelen, visible in the behandelaar werkbak (http://localhost:8142/, merel-behandelaar)
+#    but NOT claimed.
+#
+# 2. Find the parked instance and its Beoordelen task, then fire the boundary timer early:
+FL=http://localhost:8090/flowable-rest/service
+PID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"Beoordelen"}' \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["processInstanceId"])')
+TID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"Beoordelen"}' \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+TJ=$(curl -s -u rest-admin:test "$FL/management/timer-jobs?processInstanceId=$PID" \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/management/timer-jobs/$TJ" \
+  -H 'Content-Type: application/json' -d '{"action":"move"}'
+AJ=$(curl -s -u rest-admin:test "$FL/management/jobs?processInstanceId=$PID" \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/management/jobs/$AJ" \
+  -H 'Content-Type: application/json' -d '{"action":"execute"}'
+#
+# 3. Within a couple of poll cycles the task's candidate group flips to teamlead:
+curl -s -u rest-admin:test "$FL/runtime/tasks/$TID/identitylinks"   # → [{"group":"teamlead","type":"candidate"}]
+```
+
+**The path:** BPMN non-interrupting `P14D` boundary timer on `Beoordelen` → `BeoordelingEscaleren`
+external task → domain escalation worker (`BeoordelingEscalatiePump`) → Workflow Client swaps the task's
+candidate group behandelaar → teamlead (§8.2).
+
+> Both branches (escalate after 14 days; no-op when completed in time) are covered by the
+> `Een beoordeling escaleren` acceptance scenarios and the Workflow Client unit tests; the timer firing
+> and reassignment are asserted live by the verify-domain check.
+
+## S-13 — Diploma-eligibility: foreign diplomas route through CBGV-advies (#14, ADR-0016)
+
+A registration's diploma origin decides its route. A DMN `businessRuleTask` in the registratie
+process evaluates the `diploma-eligibility` decision on the `diplomaOrigin` start variable: a
+**foreign** (Buitenlands) diploma is routed through an extra **CBGV-advies** user task before
+beoordeling; a **domestic** (Binnenlands) one goes straight to beoordeling. The decision lives in the
+DMN, not in code — a beheerder can read and adjust the decision table directly.
+
+The self-service portal's eIDAS→foreign wiring is a later slice; for now the origin is submitted to
+the domain directly, so the demo drives it through the domain endpoint:
+
+```bash
+# 1. Submit a foreign-diploma registration to the domain (note the returned Location/reference):
+DOM=http://localhost:8080   # domain service
+curl -s -i -X POST "$DOM/registrations" -H 'Content-Type: application/json' \
+  -d '{"bsn":"123456782","diplomaOrigin":"Buitenlands"}' | grep -i '^location:'
+#
+# 2. Once the zaak is opened, the process parks at the CBGV-advies task (NOT Beoordelen). In Flowable:
+FL=http://localhost:8090/flowable-rest/service
+curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"CBGVAdvies"}' | python3 -m json.tool
+#
+# 3. Complete the CBGV-advies task; the case then advances to the regular Beoordelen task:
+TID=$(curl -s -u rest-admin:test -X POST "$FL/query/tasks" -H 'Content-Type: application/json' \
+  -d '{"processDefinitionKey":"registratie","taskDefinitionKey":"CBGVAdvies"}' \
+  | python3 -c 'import sys,json;print(json.load(sys.stdin)["data"][0]["id"])')
+curl -s -u rest-admin:test -X POST "$FL/runtime/tasks/$TID" \
+  -H 'Content-Type: application/json' -d '{"action":"complete"}'
+# A domestic submission (default, or "Binnenlands") skips CBGV-advies and parks straight at Beoordelen.
+```
+
+**The path:** domain sets the `diplomaOrigin` start variable → registratie process DMN
+`businessRuleTask` sets `route` → exclusive gateway → foreign: `CBGVAdvies` user task → `Beoordelen`;
+domestic: `Beoordelen` directly (§8.2, ADR-0016).
+
+> The domestic/foreign paths are covered by the `Een diploma op herkomst routeren` acceptance
+> scenarios and unit tests (the origin is carried into the process); the DMN decision and the
+> foreign→CBGV routing are asserted live by the verify-domain check.
